Problems solved by technology

[0004] In the prior art, the 3D navigation electronic map usually displays the 3D navigation scene with a fixed viewing angle in the graphical display of the current application, and the guiding viewing angle of the 3D navigation cannot be changed
Specifically, the real 3D navigation scene is usually displayed in the form of the driver's perspective, so that the driver can only watch the 3D scene from his own perspective, and cannot know the road conditions ahead of the road in advance, making it unsuitable for actual driving mode, reducing the Driver's 3D Navigation Experience

Abstract

The invention discloses a method and a device for display of true three-dimensional navigation images. The method includes providing a true three-dimensional navigation database which include a true three-dimensional navigation database containing records of navigation viewpoint changing makers, determining accurate position and navigation path of an object to be navigated, judging whether the navigation viewpoint changing markers exist within a preset front distance of the object to be navigated or not, and determining whether to change display viewpoint of the true three-dimensional navigation images or not according to the judgement result. The method and the device for display of true three-dimensional navigation images are capable of realizing automatic adjusting and changing of display viewpoint of the true three-dimensional navigation images.

Description

technical field [0001] The present invention relates to the field of navigation electronic maps, and more particularly, to a method and device for displaying true three-dimensional navigation images. Background technique [0002] With the rapid development of the information industry, car navigation technology is becoming more and more perfect, and car navigation systems are becoming more and more familiar and accepted by the public. [0003] While the two-dimensional navigation electronic map gradually matured, the three-dimensional navigation electronic map came into being. The three-dimensional navigation electronic map can more vividly express the increasingly complex urban road shape. With its real navigation visual effect, it attracts more and more users and becomes a hot spot for navigation services, especially car navigation services. [0004] In the prior art, the 3D navigation electronic map usually displays the 3D navigation scene with a fixed viewing angle in th...
